7mm rule


 

Hello,

I would like tojoin in on the new to O14 thread. I purchased a DHR locomotive and would like to build a small switching module. My problem is that I can not find any track gauges or rulers in USA.?

Where is a good UK internet store to purchase these items

Thank you,
Matt, Freeland, Maryland, USA

Matt,

As you can imagine, there isn't a huge demand for 14mm track gauges and wheel back-to-backs. One of the main roller gauge suppliers is currently offline but hopes to be back up and running at some stage: that's kbscale.com who normally?sell a variety of 14mm products. However, if you read John Clutterbuck's track-making?articles from Narrow Gauge & Industrial Railway Modelling Review (see the group wiki for a link) you will see how John makes his own from brass: some folded, and some cut and filed from heavier gauge material.

A number of suppliers exist for 7mm scale rulers, for example Expo Tools (https://www.expotools.com/acatalog/N-Gauge-Scale-Rule-74102.html).

Hope this helps,

As to a scale ruler, in a pinch a US HO ruler will work and is easily available in the States. 1:43.5 is twice 1:87. Just half measurements taken to get the 1:43.5 equivalent.?

There are two types of gauge, the roller gauge intended mainly for straight track and the three point one which automatically widens the gauge on curves. As Roy Link has? said, 14mm standards are basically EM but narrower. Buy from Carrs (C&L) a couple of EM roller gauges. Unless they have changed they are in effect a series of spacers and ?tube with a bolt through the middle. Take it apart, measure the centre tube and take 4mm off it and reassemble. Make yourself a length, say 6 inches, of dead straight track. Check that the gauge makes 14mm between the rails, From the EM gauge society buy a couple of three point gauges. Cut out at least 4mm from the centre. Fit the halves onto the rail on your straight track, smear the top with Araldite and put a plate on top. Clamp with hair clips or the like until the Araldite sets. Once solid you can use it like that or drill through and reinforce the Araldite bond with nuts and bolts, say 10 BA.

I bought a 16.5 back to back gauge, a brass block, and turned it in a lathe to the correct b to b for 14mm gauge, you don't need a four jaw chuck as you are only taking from the face.

I started in 14mm but gave up and went 16.5 as none of my friends were doing it so I couldn't run on their track. Friends matter more than dead scale. Some time ago Paul Holmes has run my De Wintons on Dinas 1869, but despite their archaic design they are in fact at least eleven years too late!

John talks about 'finescale' and I've no doubt that smaller rail and true gauge can look better, but recently I saw a good few P4 and EM layouts and though the track looks the part some of the rest? of the modelling was no better, and in some cases not as realistic as some OO layouts. The phrase may be 'total package'.

An excellent scale rule - in my opinion one of the very best - is available from CPL Products.
